    • Bartman's One Hour no stranger to late-night calls

      Around the clock service means the telephone often rings at strange hours. But, after 33 years running his Monongahela business, Tim Bartman knows there will be times when a customers call will awaken him. "That's part of the job", he said. "I don't like going out at 3 o'clock in the morning when it's zero outside, but that's what we tell people, to give us a call and we'll take care of it". "When most people call at 11 or midnight, they are expecting an answering machine and be put on a list for tomorrow. What suprises them is that they usually get somebody," he said. I've got 5 or 6 phone lines that ring to my cell phone at night. "I don't use an answering service. That's not good enough. We stand for a higher quality here." 

      The regular customers are entitled to the Bartman level of "preferential treatment" the boss said. "We have club members that pay a certain fee every month depending on which level of service they want," he said. "Those are people that are guaranteed that we will come out. "People that we install equipment for, we guarantee we wlll come out," Bartman said. "But, I'm not just an open phone book for people that can't find their regular guy and call me at 1 o'clock in the morning and want something fixed. "We'll do what ever we need to do for our customers that deal with us." Bartman said most after hours calls are either emergencies or someone who needs service promptly. 

      "The big thing is a plumbing disaster when people call. If they have no heat, unless it's zero degrees outside, most people don't even call," he said. "When people have no heat, more often than not, they'll wait until morning. All they want is their name on a list that someone will be out there first thing in the morning." Bartman has a staff of technicians that rotate weekly on-call shifts outside of the work day. Bartman doesn't go out on calls as much as he use to."I think I earned it. For 25 years, I did it all," he said.
